How DojoTally collects for you

You set up plans and late fees once. DojoTally creates each due, flags overdue ones, adds the late fee and lets the student know.

  • Online paymentsMercadoPago and Stripe on your own account, recorded automatically
  • Balance at the doorThe kiosk shows in red who has overdue dues
  • Student portalEach student sees their balance and payments on their phone
  • Payment link on WhatsAppThe agent tells students what they owe and sends the link (from the Base plan)

How we calculate it

  1. Money that comes in late per month = students × % who pay late × monthly fee
  2. Late money owed to you on average = money that comes in late per month × days late ÷ 30
  3. Money that never comes in per month = students × % who never pay × monthly fee
  4. Over a year = money that never comes in per month × 12

Late payers and non-payers are separate groups. We don't add late fees or payment processing fees.

Where the example values come from

  • 80 students, 30 % paying late, 5 % never paying and 15 days late: example values. Yours come from your list of overdue students.
  • Monthly fee: ARS 50,000 or US$150 depending on the currency, as an example. We didn't find a reliable public average of academy fees (checked on 10/14/2026): enter yours.
